You mean that ALSA driver snd_usb_audio can be a problem? Two days ago I made an experiment: - installed realtime kernel 2.6.31-11-rt -disabled EHCI in BIOS for my usb host controller - installed proprietary nvidia driver (cause I didn't want to update nouveau for old kernel and that old nouveau started only with low resolution) - run jackd with parameters frequency=48000Hz, buffer_size=64 samples,buffers_count=2 and in USB 1.1 OHCI mode my ATI controller worked without any bugs. So I think that snd_usb_audio ALSA driver work correctly. Am I right? > I have had but not recently because I switched to a newer card that uses > the latest driver, all sorts of similar problems, mainly due to the older > NVIDIA driver you have tainted your kernel with. I've installed nvidia proprietary driver only two days ago. The problem appears with both nouveau and nvidia drivers. ## Please, tell me what should I do next to get my EHCI working?
